I think the game IS arena imo. Constructed is only for tryharders copying other people's deck. Unless, ofc, you make your own decks, like me. I do hipster decks, such as:

1- full secret midgame hunter; of course the deck isn't completely solid but it's extremely hard to fight against it, since all of the hunter secrets can have great value or good combo (like buzzard + snake trap). Made it rank 5 with win streak. 2- full secret mage; not really solid compared to hunter deck, most games are decided by the first ~4 turns on whether you get an ethereal arcanist to survive and have something like counterspell to keep it alive and buff it.3- void terror; my fav own deck - uses crazy combos like sylvana's with power overwhelming, and then use the void terror to eat it, gain HUGE stats, steal a monster and do 9 dmg to face. Also good early combos like double ancient watcher, and then a 11/13 void terror on turn 3. 4- rush priest, based on things like mind blast + holy smite with spell dmg, the auchenai soulpriest, charge minions like leeroy, arcane golem, bluegill, wolfrider, etc. Not too solid but quite decent and humilliating.

Either way, felt like playing miracle rogue, it really does do miracles

So for long I've been trying to draft murloc arena decks (since i get more gold than i can use, i sometimes do random fun stuff in arena). But this one is a tough call, between skillstrike. Well I obviously still went for murloc because yolo.

Hit 12 win with druid (2nd time). I still really want to get 12-0. Seems so hard though because people have SO much luck and some decks are just terribly insane.And because I don't really play that much.

This particular druid deck went 12 because it was good anti-mage, however palas were owning me.No sick cards (except lore), but some truly sick combos such as acolyte x2 + wild pyro. Or 2 brewmasters with ancient of lore. Or as well brewmaster+ironbark on turn 10 to heal ironbark.

So far gotten 12 wins with shaman, paladin, druid & druid. I feel I could go 12 with rogue/mage no problem, however warlock & warrior are probably going to be really tricky. Probably would need something like deathwing. Hunter doesn't seem too hard you just need to get some good UTH+hyena combos.
